Eminence Commonwealth Speaker 12" 8 Ohm, 225W

Eminence Commonwealth Speaker 12" 8 Ohm, 225W

warmer, klarer und definierter Ton mit brillianter Presence.
Der Lautsprecher ähnelt im Charakter den alten JBL Gitarrenspeakers die ebenfalls mit 4" Schwingspulen arbeiteten wie man Sie aus den Fender Twin Reverb Amps der 1960er + 1970er Jahre kennt. Dort waren die JBL nur gegen erheblichen Aufpreis optional erhältlich und erfreuen sich vor allem bei Jazz- Gitarristen noch heute größter Beliebtheit.
Da JBL diese Modelle nicht mehr anbietet empfehlen wir den Emminence Commenwealth 12" als adäquaten Ersatz.
